When using SUNLU drybox on top of IKEA Lack enclosure, to make the filament traction smooth I created a filament guide adapter to be used with the lower hole on the case.
This was inspired from https://www.thingiverse.com/thing:4833453 but created from scratch, in order to make the filament hole angle higher.
To make it even smoother I glued textile cable sleeve inside the guide.
I printed it with 0.25mm nozzle and with 0.10mm detail but it should work 0.4 nozzle as well.
